Create subassemblies for Civil 3D with the user-friendly interface of Subassembly Composer. The Autodesk Subassembly Composer has been. When it comes to corridor modeling, Civil 3D provides a large number of subassembly parts right out of the box. Since these parts are also. One of the most common Sub-Components I get asked about is the Subassembly Composer for Civil 3D and so I am writing this helpful guide.

It will be directly tutorual the origin at a distance of negative Depth, which is a parameter previously defined, and no displacement in the X direction.

The information found in the help menu for each subassembly gives you more information about each subassembly, shows you its anatomy, the components for which you can override suassembly by using targets, etc.

Subassembly parts Figure 1 shows the basic anatomy of a subassembly with codes, points, links, and shape. For Delta X type BottomWidth—in this case it is going to go to the right from P2 so the value would be positive. This will be the origin and insertion point. Constant Length and Varying Slope Subassembly This subassembly works similar to the LinkWidthAndSlope generic subassembly, but this one keeps the length constant regardless of the slope.

Make sure the type is set to double, which is the type of parameter that will let you input values with skbassembly figures. Add a point component by dragging it from the toolbox and dropping it into the flowchart window. For this subassembly we will use output parameters that can be viewed as variables used for calculations.

Auxiliary points are used as references for other points and they are not shown in the subassembly. You can now save the file and close Subassembly Composer. Subassembly Composer has five sections: At this point this value is unitless—the units will depend on the units you use in your drawing. Atan Slope ; this will give you the slope in radians. From the toolbox in the Miscellaneous category, drag Set Output Parameter and drop it into the flowchart.

This subassembly works similar to the LinkWidthAndSlope generic subassembly, but composr one keeps the length constant regardless of the slope. This point will be used as the origin and as a reference for positioning the next point. He has worked in construction management and design since and has implemented and trained companies on Civil 3D for the past year.

Add a link fomposer to the flowchart; no need for points here because the link will connect to existing points. In this article we will see how to use the Subassembly Composer; we will look at its components and create two subassemblies to see how it works.

Customize It and Make It Yours When we customize a program or a graphical user ckvil it usually is because we want to modify the way things look and behave. For this link there is no need to modify anything else. This is the name that this subassembly will use in Civil subasse,bly. Now that you know how to use Subassembly Composer, go ahead and create your own subassemblies, draw them in your mind, then on paper, and then build the subassembly.

Notice that here you have to use both input and output parameters. In Subassembly Composer you can also create subassemblies that work with targets. These values are calculated and used for other parameters. Subassembly Composer is a program where you can create subassemblies from scratch and then use them in Civil 3D just like you would with any other subassembly. Subassemblies are the building blocks for assemblies in Civil 3D, and we can look at assemblies as cross sections for roads, rivers, embankments, etc.

All of this will make more sense once we start working with Subassembly Composer in the following exercises. Add another Output Parameter. The process is similar in that you have to create civll and use those parameters to define targets. You can solve this in Civil 3D if you create a closed polyline, turn it into a subassembly, then assign codes, links, and shape and it probably would be fine.


Miguel can be reached at mmedina prosoftnet. Repeat the previous steps for the other parameters and make sure your parameters match what is shown in Figure 2. From the toolbox under the Geometry category, drag tutoiral Point component and drop it into the Flowchart window.

Hover over one of the tabs subassemblyy the tool palette, right-click and select New Palette. And because we have two different options, we will use a conditional operator. Add this subassembly to the Custom Subassemblies palette the same way you did with the other subassembly.

For this point there is no need to modify anything else. Now you have two parametric subassemblies made from scratch. Name the new Palette Custom Subassemblies.

Customize sugassembly and make it yours! PI; this will convert the Atan into degrees. By doing this we are converting the grade value into a slope value. Add a point below the auxiliary point you just created and set its properties as shown in Figure 7.

Name this parameter TopWidth with no spaces.

Add another point element, which will be the bottom right corner of the subassembly. Ciivil is where you see how the subassembly looks as you are putting things together.

AutoCAD has some verticals with specialized tools to design and draft elements pertaining to different industries.
